Hereinafter, exemplary embodiments of the present disclosure will bedescribed in greater detail with reference to the accompanying drawings.In describing the present disclosure, for ease of understanding, thesame reference numerals are used to denote the same componentsthroughout the drawings, and repetitive description on the samecomponents will be omitted. Detailed description on well-known artswhich are determined to make the gist of the disclosure unclear will beomitted. The accompanying drawings are provided to merely make thespirit of the disclosure readily understood, but not should be intendedto be limiting of the disclosure. It should be understood that thespirit of the disclosure may be expanded to its modifications,replacements or equivalents in addition to what is shown in thedrawings.

As used herein, ‘base station’ generally refers to a fixed station thatcommunicates with a wireless device and may be denoted by other termssuch as eNB (evolved-NodeB), BTS (base transceiver system), or accesspoint.

As used herein, ‘user equipment (UE)’ may be stationary or mobile, andmay be denoted by other terms such as device, wireless device, terminal,MS (mobile station), UT (user terminal), SS (subscriber station), MT(mobile terminal) and etc.

FIG. 1 illustrates a wireless communication system.

As seen with reference to FIG. 1, the wireless communication systemincludes at least one base station (BS) 20. Each base station 20provides a communication service to specific geographical areas(generally, referred to as cells) 20 a, 20 b, and 20 c. The cell can befurther divided into a plurality of areas (sectors).

The UE generally belongs to one cell and the cell to which the UE belongis referred to as a serving cell. A base station that provides thecommunication service to the serving cell is referred to as a servingBS. Since the wireless communication system is a cellular system,another cell that neighbors to the serving cell is present. Another cellwhich neighbors to the serving cell is referred to a neighbor cell. Abase station that provides the communication service to the neighborcell is referred to as a neighbor BS. The serving cell and the neighborcell are relatively decided based on the UE.

Hereinafter, a downlink means communication from the base station 20 tothe UE1 10 and an uplink means communication from the UE 10 to the basestation 20. In the downlink, a transmitter may be a part of the basestation 20 and a receiver may be a part of the UE 10. In the uplink, thetransmitter may be a part of the UE 10 and the receiver may be a part ofthe base station 20.

Meanwhile, the wireless communication system may be generally dividedinto a frequency division duplex (FDD) type and a time division duplex(TDD) type. According to the FDD type, uplink transmission and downlinktransmission are achieved while occupying different frequency bands.According to the TDD type, the uplink transmission and the downlinktransmission are achieved at different time while occupying the samefrequency band. A channel response of the TDD type is substantiallyreciprocal. This means that a downlink channel response and an uplinkchannel response are approximately the same as each other in a givenfrequency area. Accordingly, in the TDD based wireless communicationsystem, the downlink channel response may be acquired from the uplinkchannel response. In the TDD type, since an entire frequency band istime-divided in the uplink transmission and the downlink transmission,the downlink transmission by the base station and the uplinktransmission by the terminal may not be performed simultaneously. In theTDD system in which the uplink transmission and the downlinktransmission are divided by the unit of a subframe, the uplinktransmission and the downlink transmission are performed in differentsubframes.

Hereinafter, the LTE system will be described in detail.

FIG. 2 shows a downlink radio frame structure according to FDD of 3rdgeneration partnership project (3GPP) long term evolution (LTE).

The radio frame of FIG. 2 may be found in the section 5 of 3GPP TS36.211 V10.4.0 (2011-12) “Evolved Universal Terrestrial Radio Access(E-UTRA); Physical Channels and Modulation (Release 10)”.

The radio frame includes 10 sub-frames indexed 0 to 9. One sub-frameincludes two consecutive slots. Accordingly, the radio frame includes 20slots. The time taken for one sub-frame to be transmitted is denoted TTI(transmission time interval). For example, the length of one sub-framemay be 1 ms, and the length of one slot may be 0.5 ms.

The structure of the radio frame is for exemplary purposes only, andthus the number of sub-frames included in the radio frame or the numberof slots included in the sub-frame may change variously.

One slot includes NRB resource blocks (RBs) in the frequency domain. Forexample, in the LTE system, the number of resource blocks (RBs), i.e.,NRB, may be one from 6 to 110.

The resource block is a unit of resource allocation and includes aplurality of sub-carriers in the frequency domain. For example, if oneslot includes seven OFDM symbols in the time domain and the resourceblock includes 12 sub-carriers in the frequency domain, one resourceblock may include 7×12 resource elements (REs).

The physical channels in 3GPP LTE may be classified into data channelssuch as PDSCH (physical downlink shared channel) and PUSCH (physicaluplink shared channel) and control channels such as PDCCH (physicaldownlink control channel), PCFICH (physical control format indicatorchannel), PHICH (physical hybrid-ARQ indicator channel) and PUCCH(physical uplink control channel).

The uplink channels include a PUSCH, a PUCCH, an SRS (Sounding ReferenceSignal), and a PRACH (physical random access channel).

Carrier Aggregation

A carrier aggregation system is now described.

A carrier aggregation system aggregates a plurality of componentcarriers (CCs). A meaning of an existing cell is changed according tothe above carrier aggregation. According to the carrier aggregation, acell may signify a combination of a downlink component carrier and anuplink component carrier or an independent downlink component carrier.

Further, the cell in the carrier aggregation may be classified into aprimary cell, a secondary cell, and a serving cell. The primary cellsignifies a cell operated in a primary frequency. The primary cellsignifies a cell which UE performs an initial connection establishmentprocedure or a connection reestablishment procedure or a cell indicatedas a primary cell in a handover procedure. The secondary cell signifiesa cell operating in a secondary frequency. Once the RRC connection isestablished, the secondary cell is used to provide an additional radioresource.

As described above, the carrier aggregation system may support aplurality of component carriers (CCs), that is, a plurality of servingcells unlike a single carrier system.

The carrier aggregation system may support a cross-carrier scheduling.The cross-carrier scheduling is a scheduling method capable ofperforming resource allocation of a PDSCH transmitted through othercomponent carrier through a PDCCH transmitted through a specificcomponent carrier and/or resource allocation of a PUSCH transmittedthrough other component carrier different from a component carrierbasically linked with the specific component carrier.

Introduction of Dual Connectivity (DC)

Recently, a scheme for simultaneously connecting UE to different basestations, for example, a macro cell base station and a small cell basestation, is being studied. This is called dual connectivity (DC).

In DC, the eNodeB for the primary cell (Pcell) may be referred to as amaster eNodeB (hereinafter referred to as MeNB). In addition, the eNodeBonly for the secondary cell (Scell) may be referred to as a secondaryeNodeB (hereinafter referred to as SeNB).

A cell group including a primary cell (Pcell) implemented by MeNB may bereferred to as a master cell group (MCG) or PUCCH cell group 1. A cellgroup including a secondary cell (Scell) implemented by the SeNB may bereferred to as a secondary cell group (SCG) or PUCCH cell group 2.

Meanwhile, among the secondary cells in the secondary cell group (SCG),a secondary cell in which the UE can transmit Uplink Control Information(UCI), or the secondary cell in which the UE can transmit a PUCCH may bereferred to as a super secondary cell (Super SCell) or a primarysecondary cell (Primary Scell; PScell).

Next-Generation Mobile Communication Network

With the success of Evolved Universal Terrestrial Radio Access Network(E-UTRAN) for the fourth-generation mobile communication which is LongTerm Evolution (LTE)/LTE-Advanced (LTE-A), the next generation mobilecommunication, which is the fifth-generation (so called 5G) mobilecommunication, has been attracting attentions and more and moreresearches are being conducted.

The fifth-generation communication defined by the InternationalTelecommunication Union (ITU) refers to providing a maximum datatransmission speed of 20 Gbps and a maximum transmission speed of 100Mbps per user in anywhere. It is officially called “IMT-2020” and aimsto be released around the world in 2020.

The ITU suggests three usage scenarios, for example, enhanced MobileBroadBand (eMBB), massive Machine Type Communication (mMTC), and UltraReliable and Low Latency Communications (URLLC).

URLLC relates to a usage scenario in which high reliability and lowdelay time are required. For example, services like autonomous driving,automation, and virtual realities requires high reliability and lowdelay time (for example, 1 ms or less). A delay time of the current 4G(LTE) is statistically 21-43 ms (best 10%), 33-75 ms (median). Thus, thecurrent 4G (LTE) is not sufficient to support a service requiring adelay time of 1 ms or less. Next, eMBB relates to a usage scenario inwhich an enhanced mobile broadband is required.

That is, the fifth-generation mobile communication system aims toachieve a capacity higher than the current 4G LTE and is capable ofincreasing a density of mobile broadband users and supportDevice-to-Device (D2D), high stability, and Machine Type Communication(MTC). Researches on 5G aims to achieve reduced waiting time and lessbatter consumption, compared to a 4G mobile communication system, inorder to implement the IoT. For the 5G mobile communication, a new radioaccess technology (New RAT or NR) may be proposed.

FIGS. 3A to 3C are diagrams illustrating exemplary architecture for anext-generation mobile communication service.

Referring to FIG. 3A, a UE is connected in dual connectivity (DC) withan LTE/LTE-A cell and a NR cell.

The NR cell is connected with a core network for the legacyfourth-generation mobile communication, that is, an Evolved Packet core(EPC).

Referring to FIG. 3B, the LTE/LTE-A cell is connected with a corenetwork for 5th generation mobile communication, that is, a NextGeneration (NG) core network, unlike the example in FIG. 4A.

A service based on the architecture shown in FIGS. 3A and 3B is referredto as a non-standalone (NSA) service.

Referring to FIG. 3C, a UE is connected only with an NR cell. A servicebased on this architecture is referred to as a standalone (SA) service.

Meanwhile, in the above new radio access technology (NR), using adownlink subframe for reception from a base station and using an uplinksubframe for transmission to the base station may be considered. Thismethod may be applied to paired spectrums and not-paired spectrums. Apair of spectrum indicates including two subcarrier for downlink anduplink operations. For example, one subcarrier in one pair of spectrummay include a pair of a downlink band and an uplink band.

FIG. 4 shows an example of subframe type in NR.

A transmission time interval (TTI) shown in FIG. 5 may be called asubframe or slot for NR (or new RAT). The subframe (or slot) in FIG. 5may be used in a TDD system of NR (or new RAT) to minimize datatransmission delay. As shown in FIG. 4, a subframe (or slot) includes 14symbols as does the current subframe. A front symbol of the subframe (orslot) may be used for a downlink control channel, and a rear symbol ofthe subframe (or slot) may be used for a uplink control channel. Otherchannels may be used for downlink data transmission or uplink datatransmission. According to such structure of a subframe (or slot),downlink transmission and uplink transmission may be performedsequentially in one subframe (or slot). Therefore, a downlink data maybe received in the subframe (or slot), and a uplink acknowledge response(ACK/NACK) may be transmitted in the subframe (or slot). A subframe (orslot) in this structure may be called a self-constrained subframe. Ifthis structure of a subframe (or slot) is used, it may reduce timerequired to retransmit data regarding which a reception error occurred,and thus, a final data transmission waiting time may be minimized. Insuch structure of the self-contained subframe (slot), a time gap may berequired for transition from a transmission mode to a reception mode orvice versa. To this end, when downlink is transitioned to uplink in thesubframe structure, some OFDM symbols may be set as a Guard Period (GP).

Support of Various Numerologies

In the next generation system, with development of wirelesscommunication technologies, a plurality of numerologies may be providedto a UE.

The numerologies may be defined by a length of cycle prefix (CP) and asubcarrier spacing. One cell may provide a plurality of numerology to aUE. When an index of a numerology is represented by μ, a subcarrierspacing and a corresponding CP length may be expressed as shown in thefollowing table.

TABLE 1 μ f = 2^(μ·)15 [kHz] CP 0 15 Normal 1 30 Normal 2 60 Normal,Extended 3 120 Normal 4 240 Normal

In the case of a normal CP, when an index of a numerology is expressedby μ, the number of OLDM symbols per slot N^(slot) _(symb), the numberof slots per frame N^(frame,μ) _(slot), and the number of slots persubframe N^(frame,μ) _(slot) are expressed as shown in the followingtable.

TABLE 2 μ N^(slot) _(symb) N^(frame,μ) _(slot) N^(subframe,μ) _(slot) 014 10 1 1 14 20 2 2 14 40 4 3 14 80 8 4 14 160 16 5 14 320 32

In the case of an extended CP, when an index of a numerology isrepresented by μ, the number of OLDM symbols per slot N^(slot) _(symb),the number of slots per frame N^(frame,μ) _(slot), and the number ofslots per subframe N^(subframe,μ) _(slot) are expressed as shown in thefollowing table.

TABLE 3 μ N^(slot) _(symb) N^(frame,μ) _(slot) N^(subframe,μ) _(slot) 212 40 4

Meanwhile, in the next-generation mobile communication, each symbol maybe used for downlink or uplink, as shown in the following table. In thefollowing table, uplink is indicated by U, and downlink is indicated byD. In the following table, X indicates a symbol that can be flexiblyused for uplink or downlink.

Technical Problem to be Solved by the Present Disclosure

There may be various types of UEs using NR, including handheld UEs,Fixed Wireless Access (FWA) devices, and vehicle mounted devices.Depending on the type of a UE, transmission power class may be setdifferently, which may be determined based on the minimum peak EffectiveIsotropic Radiated Power (EIRP) value due to beamforming supported by NRand the cumulative distribution function (CDF) value of a measured EIRP.

Depending on the type of a UE, the spherical range may be divided intofull sphere and half sphere types, and the EIRP value corresponding to x%-tile CDF may be used for distinguishing the power class of the UE.

In NR FR2, the minimum peak EIRP for each band is defined as follows.

TABLE 9 Handheld Minimum NR band peak EIRP (dBm) n257 [21.2-25.2] rangen258 [21.2-25.2] range n260 [19.4-23.7] range n261 [21.2-25.2] range

In the table above, the minimum peak EIRP is defined as the lower limitwithout tolerance. NR UE maximum output power limit is as follows.

TABLE 10 Total Radiated Power EIRP (dBm) NR band (TRP) handheld (dBm)handheld n257 23 43 n258 23 43 n260 23 43 n261 23 43

In what follows, the present disclosure proposes a method for definingpower classes for NR UEs in the mmWave band.

More specifically, the present disclosure proposes methods for using theminimum peak EIRP, the maximum output power limit, and the sphericalcoverage to determine the NR UE type.

1. First Disclosure

The first disclosure proposes to assume the same UE type withoutclassifying UEs into a handheld UE, a fixed wireless access (FWA)device, or a vehicle-mounted terminal.

Instead, the first disclosure proposes to define various terminals withsimilar minimum peak EIRP values as belonging to a single UE type.According to this disclosure, an advantageous effect is obtained thatthe number of signaling bits is reduced.

A UE type is distinguished by the minimum peak EIRP.

-   -   UEs belonging to the same UE type exhibit the same minimum peak        EIRP and spherical coverage.    -   Signaling is required to distinguish UE types.
